Description

Technical Field

[0001] This invention relates to the field of photovoltaic brackets, and in particular to a high-precision solar dual-axis linkage automatic tracking photovoltaic bracket. Background Technology

[0002] In the field of solar photovoltaic power generation, traditional fixed photovoltaic (PV) mounting systems have long dominated. These systems install PV modules at a fixed angle, and their orientation and tilt angle cannot be adjusted according to changes in the sun's position after installation. Because the sun's position changes constantly throughout the day, from sunrise to sunset, its altitude and azimuth angles continuously change. Fixed mounting systems can only ensure that the PV modules are in a relatively ideal light-receiving state at a specific time. For example, at noon, when the sun's altitude angle is high, if the tilt angle of the fixed mounting system is not set properly, the PV modules may not receive sufficient direct sunlight, resulting in energy loss. Furthermore, with the changing seasons, the sun's altitude angle and the duration of sunshine also change significantly. Fixed mounting systems struggle to adapt to these dynamic changes, severely limiting overall power generation efficiency throughout the year.

[0003] The existing public disclosure CN119675543B describes a photovoltaic support structure, which includes a support mechanism with an anti-seismic mechanism inside. Two load-bearing mechanisms are respectively installed at the top of the two support mechanisms, and a limiting mechanism is installed on the outside of the support mechanisms. The two support mechanisms can be adjusted to different positions and angles to support the load-bearing mechanisms. The anti-seismic mechanism strengthens the stability of the support mechanism, improving its wind resistance and vibration resistance. As the angle changes, the load-bearing mechanisms continuously and stably fix the photovoltaic panels. The photovoltaic support structure proposed in this solution is flexible, adjustable, wind-resistant, and earthquake-resistant, enabling the deployment of photovoltaic panels in more scenarios and maximizing land utilization.

[0004] However, the aforementioned photovoltaic support structure can only be compatible with single-sided sunlight, and the adjustment is too frequent during the movement of the sun, resulting in low power generation efficiency.

[0005] Therefore, it is necessary to provide a new high-precision solar dual-axis linkage automatic tracking photovoltaic bracket to solve the above-mentioned technical problems. Summary of the Invention

[0011] Furthermore, two first connecting seats are fixedly connected to the top and bottom ends of the movable sleeve, and the inner side of each of the two first connecting seats is provided with first bristles, and the first bristles are in contact with the surface of the threaded screw.

[0012] Furthermore, the adjusting screw includes a connecting post and two threaded rods.

[0015] Compared with related technologies, the high-precision solar dual-axis linkage automatic tracking photovoltaic support provided by the present invention has the following beneficial effects: 1. Through the coordinated operation of the rotating component and the tilting component, this invention enables the photovoltaic support to achieve high-precision tracking of the sun in both horizontal and vertical directions. The rotating component allows the movable carrier plate to rotate flexibly in the horizontal direction, while the tilting component allows the movable carrier plate to tilt precisely in the vertical direction, ensuring that the solar panel always maintains the optimal angle with the sunlight, maximizing the reception of solar radiation energy, and improving the conversion efficiency of solar energy. Compared with fixed photovoltaic support, the power generation can be significantly increased.

[0017] 3. The present invention, through the brush structure set on the movable sleeve and the slider, can automatically clean and maintain the threaded screw and the surface of the threaded rod during the operation of the equipment, reducing the interference of dust and debris on the thread transmission, reducing wear, extending the service life of the equipment, and reducing the workload and cost of manual maintenance.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 ,in, Figure 1 A schematic diagram of the overall structure of the high-precision dual-axis linkage automatic tracking photovoltaic bracket provided by the present invention; Figure 2 This is a schematic diagram of the structure of the rotating component provided by the present invention; Figure 3 A schematic diagram of the tilting assembly provided by the present invention; Figure 4 This is a schematic diagram of the structure of the movable sleeve and the first connecting seat provided by the present invention; Figure 5 This is a schematic diagram of the structure of the adjustment component provided by the present invention; Figure 6 This is a schematic diagram of the structure of the slider and the second connecting seat provided by the present invention.

[0022] In the specific implementation process, such as Figure 1 As shown, the high-precision solar dual-axis linkage automatic tracking photovoltaic support includes: a frame 100, a fixed base 2, a movable carrier plate 3, a rotating component 4, a tilting component 5, and two solar panels 6. The rotating component 4 is fixedly installed on the top of the frame 100, and the output end of the rotating component 4 is fixedly connected to the fixed base 2. The bottom of the movable carrier plate 3 is rotatably connected to the top of the fixed base 2. The tilting component 5 is fixedly installed on one side of the movable carrier plate 3, and the output end of the tilting component 5 is connected to the fixed base 2. The tilting component 5 is used to adjust the tilt angle of the movable carrier plate 3. The solar panels are installed on the movable carrier plate 3. Two solar panels 6 rotate at one end relative to each other, and the movable carrier plate 3 is also equipped with an adjustment component 7 for adjusting the opening and closing angle between the two solar panels 6.

[0023] In the above structure, the frame 100 serves as the supporting foundation for the entire bracket, providing a stable installation platform for other components. The fixed base 2 connects the rotating component 4 and the movable carrier plate 3, serving as a transition and support function. The movable carrier plate 3 is used to install the solar panels 6 and can be angled under the action of the tilting component 5 and the adjusting component 7. The rotating component 4 enables the movable carrier plate 3 to rotate in the horizontal direction, the tilting component 5 enables the movable carrier plate 3 to tilt in the vertical direction, and the adjusting component 7 is used to adjust the opening angle between the two solar panels 6.

[0024] In some embodiments, reference is made to Figure 2 As shown, the rotating assembly 4 includes a first drive motor 401, a housing 402, a worm gear 403, a worm 404, and a shaft 405. The first drive motor 401 and the housing 402 are respectively fixedly installed on the top of the frame 100. The output end of the first drive motor 401 is fixedly connected to one end of the worm 404, and the other end of the worm 404 is rotatably installed on the inner side wall of the housing 402. The worm gear 403 is fixedly installed on the surface of the shaft 405 and meshes with the worm 404. The bottom of the shaft 405 is rotatably installed on the bottom wall of the housing 402, and the top of the shaft 405 is fixedly connected to the bottom of the fixed base 2. In the above structure, the worm gear 403 and worm 404 transmission have self-locking properties, which can ensure that the position of the movable carrier plate 3 in the horizontal direction is stable when the motor stops rotating, and will not rotate arbitrarily due to external factors.

[0025] In some embodiments, reference is made to Figure 3 As shown, the tilt assembly 5 includes a fixed plate 501, a second drive motor 502, a threaded screw 503, a movable sleeve 504, and a connecting plate 505. The fixed plate 501 is fixedly installed on one side of the movable plate 3. The second drive motor 502 is fixedly installed on the fixed plate 501. The output end of the second drive motor 502 is fixedly connected to one end of the threaded screw 503. The surface of the threaded screw 503 is threadedly connected to the inner side of the movable sleeve 504. One end of the connecting plate 505 is fixedly installed on one side of the fixed base 2. The top of the connecting plate 505 is provided with a through groove 506, and both sides of the through groove 506 are provided with sliding grooves 507. The surface of the movable sleeve 504 is also provided with two opposing movable rods 508, which are slidably installed in the two sliding grooves 507 respectively. In the above structure, after the second drive motor 502 starts, it drives the threaded screw 503 to rotate. Since the movable sleeve 504 is threadedly connected to the threaded screw 503, and the movable sleeve 504 is restricted within the sliding groove 507 of the connecting carrier plate 505 by the movable rod 508, it can only move along the direction of the sliding groove 507. Therefore, the rotation of the threaded screw 503 will cause the movable sleeve 504 to move linearly in the vertical direction. The up and down movement of the movable sleeve 504 will push or pull the movable carrier plate 3, causing the movable carrier plate 3 to tilt in the vertical direction around its rotational connection point with the fixed seat 2, thereby achieving tracking of the solar altitude angle.

[0026] For details, please refer to Figure 4 As shown, two first connecting seats 509 are fixedly connected to the top and bottom ends of the movable sleeve 504 respectively. The inner side of each of the two first connecting seats 509 is provided with first bristles 510, and the first bristles 510 are in contact with the surface of the threaded screw 503. The first brush 510 cleans the surface of the threaded screw 503, removing dust and debris, ensuring smooth thread transmission, reducing wear, and extending the service life of the equipment.

[0027] In some embodiments, reference is made to Figure 5 As shown, the adjustment assembly 7 includes two first support seats 701, two second support seats 702, two adjusting screws 703, two sliders 704, two sliders 705, and a drive mechanism for driving the two adjusting screws 703 to rotate synchronously. The two first support seats 701 and the two second support seats 702 are respectively fixedly installed on both sides of the movable carrier plate 3. The two ends of the two adjusting screws 703 are respectively rotatably installed on the inner side walls of the two first support seats 701 and the two second support seats 702. The two sliders 704 are respectively threaded to the two ends of one of the adjusting screws 703, and the inner sides of the two sliders 704 are respectively rotatably connected to one side of the two solar panels 6. The two sliders 705 are respectively threaded to the two ends of the other adjusting screw 703, and the inner sides of the two sliders 705 are respectively rotatably connected to the other side of the two solar panels 6. The drive mechanism is fixedly installed on the fixed plate 501.

[0028] Specifically, the adjusting screw 703 includes a connecting post 706 and two threaded rods 707. One end of each threaded rod 707 is fixedly connected to both ends of the connecting post 706, and the other ends of each threaded rod 707 are rotatably mounted on the first support 701 and the second support 702, respectively. The helical directions of the surfaces of the two threaded rods 707 are opposite. The movable carrier plate 3 is also provided with a third support 708 and a fourth support 709. The third support 708 and the fourth support 709 are fixedly installed in the middle of the movable carrier plate 3, and the third support 708 and the fourth support 709 are rotatably connected to both ends of the connecting column 706.

[0029] Specifically, the drive mechanism includes a third drive motor 710, a first bevel gear 711, a second bevel gear 712, a first spur gear 713, and a second spur gear 714. The third drive motor 710 is fixedly mounted on the fixed plate 501, and the output end of the third drive motor 710 is fixedly connected to one side of the first bevel gear 711. The second bevel gear 712 is fixedly mounted on the surface of the connecting column 706 and meshes with the first bevel gear 711. The first spur gear 713 and the second spur gear 714 are respectively fixedly mounted on the ends of the two adjusting screws 703, and the first spur gear 713 meshes with the second spur gear 714. In the above structure, when the third drive motor 710 starts, its output end drives the first bevel gear 711 to rotate. The first bevel gear 711 meshes with the second bevel gear 712 fixed on the surface of the connecting column 706, thereby driving the connecting column 706 to rotate. The rotation of the connecting column 706 drives the two adjusting screws 703 to rotate. Since the spiral directions of the two adjusting screws 703 are opposite, and the slider 1 704 and slider 2 705 are threadedly connected to the adjusting screws 703 respectively, the two sliders 1 704 will move in opposite directions along the adjusting screws 703, and the two sliders 2 705 will also move in opposite directions along the other adjusting screw 703. The movement of sliders 1 704 and slider 2 705 will drive the two solar panels 6 to rotate around one end, thereby realizing the adjustment of the opening angle between the two solar panels 6 to adapt to different light conditions and power generation needs.

[0030] For more specific details, please refer to Figure 6 As shown, two second connecting seats 715 are fixedly connected to both sides of slider 1 704 and slider 2 705 respectively. The inner side of each of the two second connecting seats 715 is provided with second bristles 716, and the second bristles 716 are in contact with the surface of the threaded rod 707. The second brush 716 will clean the surface of the threaded rod 707, removing dust and debris, ensuring smooth thread transmission, reducing wear, and extending the service life of the equipment; It should be noted that both the first connector 509 and the second connector 715 can be removed and replaced using screws.

[0031] The working principle provided by this invention is as follows: First, the first drive motor 401 is started, and its output end drives the worm 404 to rotate. Since the worm wheel 403 meshes with the worm 404, the rotation of the worm 404 will drive the worm wheel 403 to rotate, which in turn drives the shaft 405 to rotate. The rotation of the shaft 405 causes the fixed base 2 to rotate in the horizontal direction, thereby driving the movable carrier plate 3 and the solar panel 6 installed on the movable carrier plate 3 to rotate in the horizontal direction, so as to achieve tracking of the horizontal position of the sun. Secondly, the second drive motor 502 can be started to drive the threaded screw 503 to rotate. Since the movable sleeve 504 is threadedly connected to the threaded screw 503, and the movable sleeve 504 is restricted within the sliding groove 507 of the connecting carrier plate 505 by the movable rod 508, it can only move along the direction of the sliding groove 507. Therefore, the rotation of the threaded screw 503 will cause the movable sleeve 504 to move linearly in the vertical direction. The up and down movement of the movable sleeve 504 will push or pull the movable carrier plate 3, causing the movable carrier plate 3 to tilt in the vertical direction around its rotational connection point with the fixed base 2, thereby achieving the tracking of the solar altitude angle. When the opening angle between the two solar panels 6 needs to be adjusted, the third drive motor 710 is started. Its output end drives the first bevel gear 711 to rotate. The first bevel gear 711 meshes with the second bevel gear 712 fixed on the surface of the connecting column 706, thereby driving the connecting column 706 to rotate. The rotation of the connecting column 706 drives the two adjusting screws 703 to rotate. Since the spiral directions of the two adjusting screws 703 are opposite, and the slider 1 704 and slider 2 705 are threadedly connected to the adjusting screws 703 respectively, the two sliders 1 704 will move in opposite directions along the adjusting screws 703, and the two sliders 2 705 will also move in opposite directions along the other adjusting screw 703. The movement of sliders 1 704 and slider 2 705 will drive the two solar panels 6 to rotate around one end, thereby realizing the adjustment of the opening angle between the two solar panels 6 to adapt to different light conditions and power generation needs.

[0032] It should be noted that the power supply for the above-mentioned electrical equipment is drawn from the low-voltage side of the step-up grid-connected power frequency transformer and supplied through a high-voltage input AC / DC power supply. The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
